Abstract

LA INVENCION SE REFIERE A UN SERVOMOTOR NEUMATICO DE ASISTENCIA A LA FRENADA QUE COMPRENDE UNA ENVOLTURA EN EL INTERIOR DE LA CUAL SE ENCUENTRA UN PISTON (20) FORMADO POR UN CUBO (34) Y UN CUERPO (32) Y QUE DEFINE UNA CAMARA DELANTERA (16) CONECTADA PERMANENTEMENTE A UNA FUENTE DE DEPRESION Y UNA CAMARA TRASERA (18) CONECTADA SELECTIVAMENTE A LA CAMARA DELANTERA (16) O A LA ATMOSFERA POR UN MEDIO DE VALVULA (60, 62) ACCIONADO POR UNA VARILLA DE MANDO (54) SUSCEPTIBLE DE APOYARSE, MEDIANTE LA CARA DELANTERA DEL BUZO (44) SOBRE LA CARA TRASERA DE UN DISCO DE REACCION (48) SOLIDARIO DE UNA VARILLA DE EMPUJE (52), ESTANDO UN MUELLE DE ANTAGONISTA (84) DE LA VARILLA DE MANDO (54) DISPUESTO ENTRE EL PISTON (34) Y EL BUZO (44), COMPRENDIENDO EL MEDIO DE VALVULA (60, 62) UNA MARIPOSA QUE COOPERA CON EL PRIMER ASIENTO DE VALVULA CIRCULAR (44A) FORMADO SOBRE EL BUZO (44) Y UN SEGUNDO ASIENTO DE VALVULA CIRCULAR (20A) FORMADO SOBRE EL PISTON (20), COMPRENDIENDO LA MARIPOSA (60,62) UNA MEMBRANA FLEXIBLE DE FORMA GENERAL TRONCOCONICA, Y FIJADA DE MANERA ESTANCA POR SU BORDE PERIFERICO EXTERIOR AL PISTON (20). SEGUN LA INVENCION, LA MEMBRANA FLEXIBLE (60) ESTA CONECTADA DE MANERA ESTANCA POR SU BORDE PERIFERICO INTERIOR A UNA PARTE TUBULAR RIGIDA (62) QUE SE DESLIZA DE MANERA ESTANCA EN UNA PARTE TUBULAR (22) DEL PISTON (20).THE INVENTION REFERS TO A PNEUMATIC BRAKE ASSISTANCE SERVOMOTOR WHICH INCLUDES A WRAP INSIDE WHICH IS A PISTON (20) FORMED BY A BUCKET (34) AND A BODY (32) AND DEFINING A FRONT CAMERA ( 16) PERMANENTLY CONNECTED TO A DEPRESSION SOURCE AND A REAR CAMERA (18) SELECTIVELY CONNECTED TO THE FRONT CHAMBER (16) OR TO THE ATMOSPHERE BY A VALVE MEASURE (60, 62) OPERATED BY A CONTROL ROD (54) SUSCEPTIBLE TO SUPPORT , THROUGH THE FRONT FACE OF THE DIVER (44) ON THE REAR FACE OF A REACTION DISC (48) SOLIDARITY OF A PUSHING ROD (52), WITH AN ANTAGONIST SPRING (84) OF THE CONTROL ROD (54) ARRANGED BETWEEN THE PISTON (34) AND THE DIVER (44), UNDERSTANDING THE VALVE MIDDLE (60, 62) A BUTTERFLY THAT COOPERATES WITH THE FIRST CIRCULAR VALVE SEAT (44A) FORMED ON THE CIRCULAR VALVE (44) AND A SECOND CIRCULAR VALVE SEAT (20A) FORMED ON THE PISTON (20), UNDERSTANDING THE BUTTERFLY (60.62) A FL MEMBRANE EXIBLE IN A GENERAL TRONCOCONIC WAY, AND FIXED WATERTIGHT BY ITS PERIPHERAL EDGE EXTERIOR TO THE PISTON (20). ACCORDING TO THE INVENTION, THE FLEXIBLE MEMBRANE (60) IS CONNECTED WATERTIGHT BY ITS INNER PERIPHERAL EDGE TO A RIGID TUBULAR PART (62) WHICH SLIDES WATERTIGHT IN A TUBULAR PART (22) OF THE PISTON (20).
